Lavender is a beautiful, fragrant herb that is well-loved for its calming aroma and medicinal properties. French lavender, in particular, is a popular variety that is known for its deep purple flowers and sweet fragrance. However, to ensure that your French lavender plants thrive, it’s imperative to know how much water they need.

Watering French Lavender: The Basics

French lavender plants don’t like wet feet, which means that they prefer soil that’s well-drained. Overwatering can lead to root rot, which is a fungal disease that can cause the plant to die. On the other hand, under-watering can cause the plant’s leaves to turn brown and dry up.

The amount of water your French lavender plant needs depends on various factors such as the weather conditions, soil type, and age of the plant. As a rule of thumb, young plants require more frequent watering than mature ones. Also, during hot and dry weather conditions or when the plant is in full bloom, it may need more water.

How Often Should You Water French Lavender?

French lavender plants typically thrive when they receive one inch of water every week. However, you should avoid watering them too often as this can lead to overwatering. Instead, let the soil dry out slightly between watering sessions.

To check if your French lavender needs water, stick your finger into the soil about two inches deep. If it feels dry at this depth, it’s time to water the plant.

How Much Water Do You Need to Give Your French Lavender?

The amount of water your French lavender plant needs depends on various factors such as weather conditions, soil type, and age of the plant. However, as mentioned earlier, they typically require one inch of water every week.

To ensure that your lavender plant receives this amount of water, measure the amount your plant receives during each watering session. You can do this by placing a rain gauge or a shallow container in the soil near the plant. Make sure to water the plant until the soil is moist to a depth of about six inches.

Tips for Proper Lavender Plant Watering

Here are some tips to help ensure that your French lavender plants receive the right amount of water:

  • Water your plants in the morning or evening when the temperatures are cooler. This will prevent the water from evaporating too quickly.
  • Avoid wetting the leaves of your lavender plant while watering. This can lead to fungal diseases and sunburn.
  • Use a watering can or gentle spray nozzle to water your lavender plant. This will prevent the water from splashing onto the leaves and flowers.
